Obstruction of justice is one of the most misunderstood offences in Canadian criminal law. It is often associated with dramatic conduct, such as threatening witnesses or destroying evidence, but in reality, the offence is broad, technical, and frequently charged in everyday criminal cases.
For individuals facing investigation or charges, understanding how this offence works, and where the legal boundaries lie, can make a critical difference.
What Is Obstruction of Justice?
Obstruction of justice is governed by section 139 of the Criminal Code. At its core, the offence captures intentional conduct that interferes with the administration of justice. The law is deliberately broad. It criminalizes any act that attempts to obstruct, pervert, or defeat the course of justice in a judicial or investigative process. Importantly, the offence does not require success, an attempt alone is enough.
The Two Types of Obstruction Charges
Section 139 distinguishes between two categories:
1. Obstruction Relating to Sureties. This applies to situations involving bail, such as:
-
- Paying or offering to compensate a surety
- A surety accepting payment in exchange for supervising an accused
These cases are less common but still prosecuted.
2. General Obstruction (Most Common). This is the broader category most people encounter. It includes any intentional interference with an investigation or court process, such as:
-
- Encouraging a witness not to testify
- Asking someone to change their statement
- Offering money or benefits to influence evidence
- Interfering with jurors
- Misleading police in a way that impacts an investigation
Indirect conduct, such as asking a third party to intimidate a witness or to delete/withhold/destroy evidence, can qualify.
Key Legal Elements the Crown Must Prove
To secure a conviction, the prosecution must establish several essential components.
1. An Act That Interferes With Justice. The conduct must have a tendency to interfere with the course of justice, even if no actual harm occurs. This includes:
-
- Police investigations
- Ongoing court proceedings
- Even anticipated or proposed proceedings
In other words, obstruction can occur before charges are ever laid.
2. Course of Justice. The law applies broadly to the administration of justice, including:
-
- Criminal investigations
- Court proceedings
- Administrative or quasi-judicial processes
The “course of justice” begins as early as the investigative stage.
3. Specific Intent. This is where many cases are won or lost. The Crown must prove that the accused had a specific intent to obstruct justice, not merely that they performed the act. This means:
-
- A mistake, poor judgment, or panic is not automatically enough
- The conduct must be deliberate and aimed at interfering with justice
However, intent can be inferred from circumstances, which often makes this a highly contested issue at trial.
There is no requirement that the obstruction succeed. Even if the witness still testifies, or the investigation proceeds normally, the offence can still be made out. The law only requires the risk that justice could be obstructed.
Can Silence or Non-Cooperation Be Obstruction?
A common concern is whether refusing to speak to police can lead to an obstruction charge. The answer is generally no. You have a constitutional right to remain silent. Exercising that right, without more, does not amount to obstruction.
However, the situation changes where someone provides false information or takes active steps to mislead or interfere. At that point, the conduct may cross into criminal territory.
Examples of Obstruction of Justice
Courts have found obstruction in situations such as:
- Asking a witness to retract a statement
- Offering money to avoid testimony
- Interfering with evidence or investigative steps
- Attempting to influence jurors or decision-makers
Even seemingly minor actions can trigger charges if they are purposefully aimed at undermining the justice process.
Penalties and Consequences
Obstruction of justice is a hybrid offence, meaning the Crown can proceed by summary conviction (up to 2 years less a day and/or a fine) or indictment (up to 10 years imprisonment). A conviction can also impact employment opportunities, immigration status, and professional licensing.
There are no mandatory minimums, but the offence is treated seriously because it strikes at the integrity of the justice system.
Defending an Obstruction Charge
Obstruction cases are often highly defensible, particularly where intent is unclear. Common defence strategies include:
- Challenging Intent: Was the accused truly trying to obstruct justice, or simply acting out of confusion, panic, or poor judgment?
- Lack of Connection to a Proceeding: Did the alleged conduct actually relate to a real or contemplated investigation or proceeding?
- Ambiguity in Communication: Statements taken out of context, especially text messages or recorded calls, may not meet the legal threshold.
- Charter Issues: If police conduct violated constitutional rights, key evidence may be excluded.
Why Early Legal Advice Matters
Obstruction charges often arise unexpectedly, sometimes layered onto an existing investigation or charge. Because the offence is broad and intent-driven, early statements to police can be misinterpreted, casual communications (texts, calls) can become evidence, and strategic decisions early on can significantly affect the outcome.
